Simplex typewriter, early 20th-century artwork. This simple design of typewriter was developed by the Simplex Typewriter Company of New York, USA, first appearing in around 1892. The wheel was rotated to the required letter and pressed to type that letter. This was much slower than keyboard-operated typewriters and the Simplex soon became obsolete, surviving only as a toy for children. Artwork from the 26th volume (second period of 1900) of the French popular science weekly 'La Science Illustree'.
